It depends on the variety of pipevine you have. The fimbriata is a low grower and doesn't vine out very much. The elegans does vine and get thick, as shown in my pic, but it dies back in the winter, or at least that has been my experience. The trilobata vines out, but at a slower rate than the elegans. This is the first year I have had the trilobata growing in the ground so I don't have as much info on this species. The elegans is too toxic for the pipevine swallowtail, but it will host the gold rim swallowtail. If you would like some seeds for the fimbriata or elegans, I have some to share. Send me an email for info on sending a SASE.
